Audio Typist

I have approximately 20minutes of audio recorded from a meeting that I need turned into a transcript. The files are in a *.amr format as they were recorded using a voice recorder on a smartphone but I'm sure they can be converted to any other kind of digital file.

The subject area is construction contract discussions. For someone who is proficient at this I imagine it's no more than a couple of hours work.

There are likely to be 2 or 3 more meetings of a similar length that will need transcribing over the next 6 weeks.
